Title: Automatic shut-off valve device
Inventor: OGURI YASUO
IPC: F16K31/02
Filed: 1990-02-26
Abstract: PURPOSE:To make an automatic shut-off valve device compact by providing such an arrangement that the opening and closing operation of a control valve may be carried out mainly by a cylindrical shape piezoelectric element having electrodes at its inner and outer surfaces, the piezoelectric element being arranged in an insulated condition, perpendicular to the inner wall of a casing. CONSTITUTION:A cylindrical piezoelectric element 13 set at the inner peripheral wall of a casing 14 is retracted axially so as to open a control valve 12. With this arrangement, a second space 8 is communicated with a pressure relieving hole 10 so that liquid filled in the second space 8 is discharged through an outlet port 2. As a result, the pressure balancing condition between first and second spaces 7, 8 are unbalanced so that the pressure of the second space 8 becomes negative, and accordingly, a valve body 5 is moved upward overcoming the force of s spring 6 so that the outlet port 2 falls into an opened condition. Next, when the power supply to the piezoelectric element 13 is interrupted so as to close the control valve 12, the second space 8 is filled therein with liquid so that the pressure balancing condition between the first and second spaces 7, 8 is gradually set up, and accordingly, the valve body 5 is moved downward by the downward force of the spring 6 so that the outlet port 2 is closed.

Abstract: The business or other institution is provided with two complementary series of blank form parts. One of these contains one or more elements of a form of construction (multiple ply, window, glassine-patched window, glue spots, patches or strips) which would make it incompatable for use with today's commercially predominate non-impact printers. The other contains none of such elements and is suited for being run through a business computer-controlled non-impact printer for the purpose of printing of variable information thereon, and of being thereafter assembled and united increment for increment with form parts from the first series, using presently available assembling and uniting apparatus, whereupon the united forms may be successively severed into thus individualized communications and dispatched to their respective addressees.

Abstract: PURPOSE: To isomerize one or more types of 8C alkyl aromatic hydrocarbons, by bringing the hydrocarbons into contact with a specific catalyst having a high activity and selectivity capable of suppressing side reactions, e.g. disproportionation and transalkylation.  
     CONSTITUTION: At least one type of 8C alkyl aromatic hydrocarbon in the gaseous phase is brought into contact with a catalyst consisting of zeolite, wherein at least 50% of ion exchangeable alkali metal or alkaline earth metal ions of natural zeolite which belongs to the chabazite family are exchanged with hydrogen ions, at 200W 700°C and 0W100 kg/cm 2 G and a space time velocity of 0.1W20V/V /hr in the presence of hydrogen gas and isomerized. The preferred zeolite has a relatively small pores of 3W6Å. The hydrogen-type zeolite is obtained by exchanging with ammonium ions and by heating at 250W600°C to expel NH 3 .

Filed: 1978-04-19
Abstract: PURPOSE: To enable the failure of measuring diaphragm to be detected in the state of being mounted to plant by providing a device of detecting the failure of the measuring diaphragms to the primary sealing liquid side of the diaphragms which receive measuring pressure.  
     CONSTITUTION: The measuring pressure P of the high temperature metal fluid 1 passing the inside of piping 2 is transmitted to a pressure transmitter 13 by way of the diaphragm 5 of a vessel 4, the sealing liquid 7 in a capillary tube 8, the diaphragm 10 in a vessel 9 and secondary sealing liquid 11. To detect the failure of the measuring diaphragm 6 in the state where the measuring pressure P in being applied to the plant side, a valve 14 is opened to apply the pressure higher than the measuring pressure P, then if the measuring diaphragm 6 has not caused failure, the pressure corresponding to the pressure applied is sensed in the pressure transmitter 13 but if the diaphragm 6 has caused failure, the pressure sensed in the pressure transmitter 13 does no longer coincide with the pressure applied.

Title: Gaas wafer machining method
Inventor: AKIYAMA HIROKI
IPC: B24B1/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion of the thicknesses of wafers and also provide a GaAs wafer machining method excellent in flatness. SOLUTION: A grinding (14) is performed by a surface grinding machine before the lapping of a GaAs wafer (16) is performed. By this, the thickness of each wafer is arranged and, therefore, it becomes necessary to manage wafer numbers and measure the thickness of the wafers one by one for etching. As a result, the dispersion of thickness of each wafer is reduced, and its flatness is increased remarkably. When a grinding wheel of No. 1000 to 1500 is used for the flat grinding machine, less scores occur on the surface of the wafer at the time of lapping.

Abstract: PURPOSE:To save the manpower of maintenance work, to prevent the erroneous setting of station information and to speedily start service for a portable telephone set user by automatically executing registration and setting from a radio base station being an extension object for a host controller. CONSTITUTION:The type of a self unit, a unit number, the number of software versions and service which can be supported, etc., are previously stored in the radio base station 7 as data. Information is transmitted to a radio base stations controller 5 or a network service controller 3 with the supply of power as a turning point.
